COORDINATE INPUT DEVICE WITH DISPLAY

摘要

PURPOSE:To prevent the display disturbance of a liquid crystal panel caused by the pressure of an input pen and also to prevent the damage to a glass plate due to the impact and the scattering of the broken glass pieces without increasing the cost. CONSTITUTION:The safety glass is produced by adhering a 1st polarizing plate 6 of a resin material and a 2nd resistance sheet 2 of a glass plate together via an adhesive layer 14. In such a constitution of the safety glass, the breakage of the glass plate due to the impact can be prevented and also the scattering of the broken glass pieces can be prevented with no increase of the cost. The sheet 2 is never bent by the pressure of an input pen 28 since the sheet 2 is made of a glass plate, and the distortion of a liquid crystal panel 52 due to the pressure of the pen 28 can be prevented. Then it is possible to prevent the display disturbance of the panel 23 due to the pressure of the pen 28.
